Abstract (Abstrak)

Abstract. Tofu dregs are industrial waste that can be used as a source of carbohydrates. However,
its use in feed formulations is limited because it contains high crude fiber and low quality. The
fermentation process uses a mix of microorganisms. proven to improve the nutritional quality of
tofu pulp. This study ams to determine the dosage of fermented tofu pulp in feed against feed
amino acids, nutrient digestibility and juvenile food conversion ratio (FCR) of vaname shrimp.
The study was designed in a completely randomized design with treatment of 4 doses of fermented
tofu pulp in the feed, namely 5, 10, 15 and 20%. The feed was given as much as 10% of total body
weight / day to juvenile vaname shrimp measuring 0.5 g per individual kept in a glass aquarium
with 20ppt media passage for 60 days. Amino acid measurement results are within the range
sufficient for the needs of vaname shrimp. Analysis of variance showed that treatment had a
significant effect on total digestibility, protein, crude fiber, carbohydrates and fat, but not on FCR.
The highest yield was shown at a dose of 15% protein digestibility (85.62±1.576), crude fiber
(87.30±1.117), carbohydrates (90.67±1.231) and a dose of 20% fat digestibility (98.75 ± 0.070)
and total digestibility ( 79.70±0.222), the FCR ranges (3.237±.0.35) to (4.141±.0.64). The dosage
of fermented tofu dregs with mixed microorganisms can be used 15% in the feed formulation.
